A Return to Fun funfun.email/p/return-to-...

I disappeared off the face of the earth, no notice, no goodbye. I was in the middle of weekly chronicles, a series on D3.js - and suddenly I was just gone. An explanation and apology is in order.

Swede here, 1-2 is actually not long enough to be an actual vacation. Seriously, 2 weeks is barely a meditation retreat.

Apologies - I mean what is the “manual” part here? I don’t understand that part of the sentence structure in the OP. If this is an automated system test, what is the manual part of it?

Mattias Petter Johansson (MPJ) @mpj.fff.dev · 14/06/2025

But wasn’t the car manually driven at the point of the test? I.e. not full auto pilot which is the system that would have school bus training. I’m kind of confused about the parameters of the test

I am reading Daniel Levintins excellent book ”The Organized Mind” and this part perfectly explains why I sometimes get stuck in multi-hour obsessive TypeScript rabbit holes to create the perfectly (unnecessary) typed expression for a problem.

As such, if we can make things like clocks but that FEEL more like time (and I suspect that the sun must be heavily involved here) and find a more visceral standard we can help a lot of people

Oh my god this is amazing!! I have been obsessed with increasing the “viscerality” of time since I learned that a core contributor to the ADHD symptom cluster is having a neurology with a malfunctioning internal clock (an actual measurable part), massive amounts of other problems arise from that

thank you soooo much for this, Nicole! 💛I have never thought about the pull to open up the black boxes to be related to ADHD before (and when I think about it maybe I think it's rather more my less dominant autistic flair - but hey I'm not a neuroscientist, and it's an interesting thought 😃

Aren’t this a weeeeee bit … I dunno. Are you genuinely interested in having a discussion about this and and find nuance or do you just want to state your opinion and aren’t actually open to there being something interesting here? Cool if not, just want to know before I engage further.

I understand why one would be sceptical of a claim like this, but having watched West Wing I’m not sure why you’d have THAT high opinion of polls that a mere “lol” is sufficient. Prediction markets is a very old concept and isn’t tooooo shitty at predicting en.m.wikipedia.org/wiki/Predict...

Also it’s not quite clear to me to what extent this is a critique of prediction markets in general or polymarket (the crypto degen comment implies this, but not sure)? If it is the latter, did PM deviate significantly from other prediction markets?

Mattias Petter Johansson (MPJ) @mpj.fff.dev · 09/05/2025

Sorry, that was a bit facetious. I understand the critique, and maybe it’s warranted, but critiquing predictions is somewhat problematic if one does not do predictions themselves - thus my question implied what the OP used for prediction themselves (and how that went)

Hmm, I’m perhaps not quite understanding of the word, not being a native English speaker, but ethnicity isn’t something in DNA? If it was, we would call it biological. What does she mean, exactly, and what do you mean, when you use the term ethnicity? It seems like a word sloppily?

How many % of the currently experienced value of large language models come from the fact that they ingest in a way that a traditional search engines would have been sued and blocked to oblivion if they did? And how expensive would they be if they paid fairly for the privilege?

New article by me! It's a common mistake to think the TFR is a prediction of the average number of children women will have over their lifetimes. But it's not. The TFR can decline even when the eventual number of children per woman stays constant or even increases; the opposite can happen too. 🧵

A line graph compares two measures of fertility rates in Sweden over time: the total fertility rate and the completed cohort fertility rate.

The total fertility rate is depicted using a red line, which shows a downward trend starting around the early 1900s, with fluctuations and a gradual decline to about 1.5 in 2022.

The completed cohort fertility rate is illustrated with a blue line, with the time axis showing the women's birth year. It shows an initial decline followed by a stable fertility rate.

A note at the bottom states that the completed cohort fertility rate has been shifted by 30 years to align with the respective birth years of women. The data source is the Human Fertility Database (2024) and the chart is published by Our World in Data.
